Sonic was first introduced to the world in 1991 with the release of the original Sonic the Hedgehog game for the Sega Genesis. The game was an instant hit, and Sonic quickly became a household name. He continued to star in successful games throughout the 1990s, including several classic titles like Sonic & Knuckles and Sonic Adventure. By the early 2000s, Sonic’s popularity had begun to wane somewhat, but he made a big comeback in 2006 with the release of Sonic the Hedgehog 2006. This game was widely criticized by fans and critics alike, but Sonic’s popularity has remained strong nonetheless.
